vThis invention relates to improvements in miter gauges for use in connection with shaving machines for Cutting printers, 'borders and theprimary object of the invention is to 'i provide a lmiter gaugeA so constructed that composite borders, or in othei` words, borders comprising monotype and linotype strlps, and likewise material used in connection with the strips to provide for relative spacing of the same, andithus provide for impression of spaced border lines without the necessity of performing this work by hand, and thus eliminating the errors which are liable to' be; made where strips of different pica are to be cut, and it is necessary to calculate, with great accuracy, thecuts to be made.

Another object of the invention is to provide a miter gauge for use in Cutting the strips ofva printens border, simultaneously -in groups, so that, where the border is for example to be twenty picas square, four groups may be mitered-without any readjustment of the mitering gaugefor each cut, and, if a rectangulai'border is to be cut, two

, groups may successively be cut with one adjustment of the miter gauge, andthe remaining two groups cut by a'second adjustme'nt of thverrniter gauge. This provides for mitering of a graduated size of several types of strips, simultaneously, and so that the groups of each, when assembled, will form a perfect rectangle or square.

Another object of the invention is to provide a gauge of the class described by the use l of which several strips of linotype or monotype border, or a combination of the two may be mitered face up.

Another object of the invention is to pro- Vide a miter gauge by the use of which an as- -semblage of strips may be cut, simultaneously, with extreme accuracy and without likelihood of any errors being made.

Another object of the invention is to pro- Vide a gauge of the class described by the -use of which the point system of calculating is eliminated and the necessary measurements of cuts are made by the mechanical mechanism, thus avoiding possible waste through limproper cutting of the material.

This invention also consists in certain other Serial No. 410,181.

features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated` in the accompanying drawing and specifically pointed out in the appended claim.

In describing my'invention in detail, reference will be had to the accompanying drawings wherein like charactersdenote like or corresponding parts throughout the several views, and in which Figure l is a plan view illustrating the miter gauge, embodying the invention, mounted upon the sliding saw table of a miter machinel and illustrating the position of the gauge with respect to the saw and to thefixed or stationary saw table. a

' Figure 2 is a view in end elevation of the initer head of the gauge embodying the invention. w

Figure 3 is a side elevation of the miter head of the gauge.

Figure 4 is a plan view of a modified form of miter head for use in simultaneously cutting a plurality of border pieces..

mitering saw being indicated by the numeral 3.v VThe gauge compri'ses a base member which is indicated in general by the numeral 4 and this base. member whichlis prefferably in the nature of a casting is mounted upon the table 1 by a pivot screw 5 connected to the table 1 and held in positions of adjustment about the pivot screw 5, by a lock pin, which is indicated by the numeral 6.

iThe body 4, at one side is provided with a thickened portion having a plane or right line face 4' against which the material to be mitered may be disposed, and in the upper face of this portion there are formed a series of grooves 7 of the form of one section of a helical screw thread, and a groove 8 is formed longitudinally in the said upper face o f the extension and parallel to the series of threadgrooves 7. i The gauge head is indicated -in general by the numeral 9 and the same comprises a body which is of trapezoidal form, one inclined side of which is indicated by the numeral 10 and is presented at an acute angle to the forward face of the extension or thickened port-ion of the base 4. From the narrow side of the body of the head 9 there extends a portion 11 which is recessed at its onter side as indicated by the numeral 12 and this portion has a substantially flat under side, which is designed to rest upon the upper side of the thickened portion of the base 4G. portion 13 of the extension 11 being located in confronting relation to the inclined side 10 of the head 9.

Within the recess 12 there is mounted an exteriorly threaded sleeve 14, a shaft 15 extending thrn the sleeve and being onrnalled in its ends at the portions of the extension which constitutes the end walls of the recess,

i The threads of lthis sleeve eng'age, at the under side of the sleeve, in the thread grooves 7 and it will be nnderstood that by rotating the sleeve, the gauge may be moved longitudinally along the base so as to determine the i distance between the face 10 of the gange head and the saw blade.y

In order that the gauge head 9, may be held in the different positions to which it be adjnsted in the length of the base, a set screw 16 is threaded thrn a boss 17 extending dewnwardly ireiii the Dart' 13, end the inner Side ef Whieh heise eppeeee the reiei-ively edjacent side of the gaug'e head 9, which in turn, ae previeiiely stated, eiises'ee ee'eiiiet .the forward side of the base 4, the said boss 17 engegins elidahly in the sreeve ei' .Channel 8, and the inner wall of the recess 12 being cut away as indicated by the nnmeral 18, so to accommodate the head of the set scr'ew 16. finger piece 19 extends from the head of the set screw into the cut anfl'v Dortion 18 and the niovenient of the finger piece is limited by its engagement with the end walls of the said cut away portion 18,.

Fignre i illustrates a miter head which may be empleyed for Cutting' a pliiieiity ef berler pieeee, Siiiiiiltaneeiislr, and iii this. figlire the head is indicate'd by the nnmeral 20 and the portions thereof which correspond to the 'portions 11 of the previously described ernbodiment are indicated by the numeral 21, The face of this head which corresponds to the face 10 of the head of the previously de scribed embodirnent is formed with a plurelity ef netehes 22 having their Welle at right angles to each other, and, in the use of this head, the ends of the miter pieces, to be mitered are disposed in respective ones of these notches.

In the, .embediment of the, invention shown in Fignre 5, the head, which is indicated by the mimeral 23, ie forlned, in its ansular face with a plurality of notches 24 which are of the form shown in this fig'ure of any other angular formation desired. In this figure the extensions corresponding to the extensions 11 and 21 of the embodiments shown in F igures 1 andd, are indicated by the numeral 25, .and in any, or all, of the forms, these extensions may be altered in any manner to permit the head to be used in connection with any and all types of mitering machines, where possible.

What I claim is A mitering gauge comprising an elongated base pivoted adjacent one end to the movable tableof a sawing machine with one end arranged adjacent the saw of the machine, means to hold the base in adjusted positions on the table, said base having a thickened poi'teii et One. Side pi'eviding a Plane Werk face against which the material to be mitered niay be placed and having` a groove extend ing parallel and in spaced relation to said face, feed teeth formed on the thickened portion of the base adjacent the groove, a gauge body ei' irapezedal Share having Oiie side inclined and disposed at an acute angle to said work face of the thickened portion of the base and providing a narrow side to the body, a bifurcated portion for-med on the narrow side of the body and providin' spaced arms traversing` the groove and fee ,i teeth and resting on the upper face of said thickened po-rtion of the base, a feed nut jonrnalled to the arms and meshingr with the teeth to permit adjustinent of the body along the work face and toward and from the saw, a boss on the bifurcated portion and extending'V into. the groove, a headed set bolt threaded to said bossV and located between the opposing walls of the groove, and a handle secnred to the headed set bolt for turning the latter against the wall of the groove lying' adjacent the work face of the base to lclamp the body in various adjnsted positions.
